Abstract: A system for controlling vehicles (20) to provide transportation services without need for human intervention. A database (10) stores records each documenting needed transportation services. Processing circuitry (which may be one or several networked computers) performs a dispatching process (26) which reviews these records, locates records indicating a need for immediate transportation service, and instructs vehicles to provide the service. The processing circuitry also performs a monitoring process (28) which monitors vehicle activities by reviewing the records, and automatically obtained vehicle activity information, to identify transportation services which are not being adequately provided, and refer these to human dispatchers (16) for special attention. A variety of methods for obtaining and updating vehicle activity information are disclosed, as are various applications for the system.
